Me; WordPress; and the Future

As those at WordCamp Gold Coast recently found out(Wow, this past month has flown by!), I’m now listed on!/automattic/automatticians/members!.

Yup. I’m an Automattician (Pst. That means I’ve been hired by Automattic)

So where does this leave my other projects:

  • My plugins will continue to be developed in my spare time.
  • My other random WordPressy projects may get some attention in my spare time, as they always have
  • I’m ceasing all development on to focus my efforts on
    ..just kidding, My involvement on will continue as it has in previous years, hopefully better than ever, whilst working on won’t be my day job, I’ll be able to give it the attention it deserves. was born out of, and I doubt I’d be anywhere near the first without the latter!
  • In other words – Life as normal.

Tonight marks the end of my 3 weeks Support Rotation my first week doing Development (It’s taken me a week to hit publish on this post..), from here on, I’ll be known as a Renewable Engineering Specialist, Yeah, you have to love the Tech. titles!

I’m quite proud to be able to say Automattic is my “place” of work, I’m looking forward to learning a whole lot more off the amazing people who I already know (and the many who I haven’t met) at Automattic – not that there’s too many to meet, with Automattic having just crossed the 100 employee mark, that’s not bad for a company who’s primary product handles over 250 million unique users per week. It’s also nice to see the Automattic population in Australia explode, up from 1 a month ago, to 4 of us!

Questions? :)
(better make them good ones.. so no questions on this ever-evolving design huh? You’ll be glad to know I’ve not been hired as a designer!)

PHP based mail server; Release Day

So the day has come, I’m a modern web developer come sysadmin. One thing that I have learn’t over time, is rely upon others for critical systems! as a result, I outsource Mail to Google Apps and DNS to Point HQ , they’re experts at both, they keep my email up 99.9% (or something) and my DNS systems running smoothly..

But being a web developer, I like tinkering with my web server configuration! As a result, I run a VPS for my http serving which combines a special blend of Nginx, Apache, PHP-fpm, mod_php and MySQL.. For the last 2 years this setup has been running awesome, but I’ve found one thing that was lacking.. being able to receive and act upon emails to my vps. With all mail being handled by Google Apps, I couldn’t just watch the local mailboxes.

The obvious way forward was to install a mail server onto my VPS to process incoming email. Long story short, email servers suck. While researching, I came up against the fact that every mail server out there was designed for being a proper mail server.. Not what I wanted, a server to process emails..

I could ramble, but skip to here if you don’t care about the back story above.

Today I give you: A PHP based Mail server, It’s written in pure PHP, it receives SMTP data on STDIN, and responds on STDOUT, perfect for use with xinetd.

I originally started out with code from: however, fast replaced it with a home grown version, and have now expanded further to today’s class based approach.

This isn’t, and hasn’t been, designed for high load that being said, It’s received over 5,000 spam emails last month with little impact upon the VPS.  (who knew that spam bots just connect to port 25 on random IP’s??)

This is designed for a single-user situation, since PHP is a scripting language running as a single user, this can’t switch to the correct users account for processing or anything.. Doesnt suit everyone.. but works

This relies upon an external application to handle the TCP -> Stream conversion, a future release might daemon itself and use sockets to accept connections, do some pcntl_fork()’ing for individual connections, and even posix_setuid() to set the effective user.. but that’s filed into the Future Release bucket.

There is no support at all. although, if you throw a comment on this post, I might respond if I’ve got time. hopefully it should be reasonably straight forward to understand.

Licensing is also left sketchy for now, See the mail-server.php header for a initial custom license, tl;dr: You may use it for commercial and personal use, you must however credit, don’t fork/rename/charge for it, but give it to your friends.. always refer to the license in the header however, as that’s the only valid source of licensing details.

No External libraries required, Aside from the previous mentioned PHP and XInetd (or similar) to handle the connections. Oddly enough, It doesn’t even require WordPress (what a shock huh? – Stay tuned, I’m sure you’ll see WordPress as a Email Client soon enough with the integration of this ;))

This is NOT a relay mail server, It’s been designed to process incoming mail, and discard mail for addresses which it doesnt know. It will not forward mail on for you. Please check that you don’t conflict with sendmail on your own system, I think I have mine set for sendmail on loopback, and this on the external interface or something like that.

You can get the code from my SVN: – Please note, this is a READ ONLY repository, if you find a bug and would like to submit it, for now, just sent it over to me at contact [at]

 Integrating with Xinetd:

How I have it running is as follows: /etc/xinetd.d/d-mail

service smtp {
        port                    = 25
        bind                    = YOUR IP ADDRESS
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = USERID TO RUN IT AS
        server                  = /path/to/mail-server/mail-server.php
        instances               = 10
        nice                    = 10
        disable                 = no

That limits connections to 10 active at a time (instances) which works well for me, that should hopefully prevent overloading.

What emails am I processing? Well, the examples should suggest that to you! SVNSync to automatically sync up a local repository with a remote repository which I don’t have admin access on for one, SVN update on a local WordPress installation (This site! It’s running on the latest WordPress trunk release within a few seconds of each commit) and there’s a few domino effect processing I’d like to do as well (ie. Alter mailing list posts to selectivly ignore certain things, Remove partial content from svn emails (I don’t want to see a 100kb minified css file in a commit email!). I’ll publish those details later when I get to it!

Magic 8 Ball Example! 

Included in the SVN repo, is a single Example plugin. A Magic 8ball extension, send an email to it with a question in the subject, and it’ll reply with an answer.

You can test this out by emailing 8ball [at] and seeing if it replies (It better!)


So go forth and download/run/test out the PHP Mail Server!  Download from Send patches to contact[at], oh, and test it out by sending an email to 8ball  [at] with a question in the subject!

Twenty Eleven Theme Colour Palette

As a follow up to my previous post: WordPress 3.2 Admin Colour Palette I was asked if I could do a Twenty Eleven version. See the previous post for the script used.

Standard “Light” colour scheme


Alternate “Dark” theme

Just a note here, Due to TwentyEleven’s structure, some of the colours in the above light theme will be used as part of this colour scheme, this is just for visual information purposes.
